Direct evaporation integral heat pipe exchanger

Abstract

The invention discloses a direct evaporation integral heat pipe exchanger, which comprises a condensation end and an evaporation end, wherein the condensation end and the evaporation end are combined and mounted into a whole; the condensation end comprises a wet film, a sprayer, a water tank, an intake air fan and a condensing working medium coil; the intake air fan is positioned between the wet film and the condensing working medium coil; the sprayer is positioned above the wet film; a water inlet of the sprayer is connected with a water outlet of the water tank through a water pipe; the evaporation end comprises an outtake air fan and an evaporating working medium coil; the evaporating working medium coil is positioned on the air outlet side of the outtake air fan; and the condensing working medium coil and the evaporating working medium coil are connected through a connection working medium pipe and are separated through a thermal insulation separation plate. According to the invention, the efficient direct evaporation integral heat pipe exchanger is formed by applying the direct evaporation cooling mode, which has a cooling effect similar to that of the traditional water cooling mode, to a heat pipe system, in this way, air cooled through direct evaporation efficiently cools the condensing working medium coil, and the efficient cooling effect and the high energy saving rate of the integral heat pipe exchanger for indoor air are ensured.

Description

technical field [0001] The invention relates to a heat exchanger used for temperature regulation and energy saving in machine rooms, base stations and buildings, in particular to a direct evaporation integrated heat pipe heat exchanger. Background technique [0002] The report of the US Environmental Protection Agency (EPA) pointed out that in 2006, US data centers consumed 61 billion kilowatt-hours of electricity (61 billion kWh), a figure that more than tripled compared to 2000. It accounts for 1.5% of the total electricity consumption in the United States that year, and the electricity bill is about 4.5 billion US dollars, which is equivalent to the average electricity consumption of 5.8 million American households. [0003] In China, the energy consumption of data centers is equally astonishing. According to analysis, the power consumption of data centers in 2009 reached 36.4 billion kWh, roughly equivalent to 1% of the national energy consumption. [0004] In the tot...

This determines that the traditional heat pipe heat exchanger can only be started and achieve energy saving effect in a very limited time of the year when the outdoor temperature is low and there is a sufficient temperature difference between indoor and outdoor; Large-scale promotion and application of energy conservation can only be carried out in regions with lower average annual temperatures (such as northern and western regions), and there is no large-scale promotion in regions with higher average annual temperatures (such as southern regions, etc.) and apply the conditions

[0008] At present, the cooling methods used in traditional heat pipe heat exchangers are divided into two types: air-cooled and water-cooled: (1) Air-cooled heat pipe system: that is, outdoor cold air is used as the cold source of heat pipe cooling. The advantage of the air-cooled heat pipe system is that the investment It is suitable for the energy-saving transformation of new and old computer rooms. However, due to the low efficiency of the air cooling system, the energy saving energy and energy saving rate of the air-cooled heat pipe system are significantly lower than that of the water-cooled heat pipe system; (2) The water-cooled heat pipe system: that is, the use of Circulating water with low outdoor temperature is used as the cold source of heat pipe cooling. The advantage of water-cooled heat pipe system is that due to the high efficiency of water cooling, the energy saving and energy saving rate are higher than those of air-cooled heat pipe system. However, due to the construction of water circulation system , resulting in a large investment in this water-cooled heat pipe system, and it is not suitable for the energy-saving renovation of the old computer room, only applicable to the energy-saving project of the new computer room
